Little Men #10-Lightkeeper

These benevolent mechano-spiritual entities wander the cave systems of the UnderDark, providing illumination and guidance to travelers who have lost their way. It is believed that they were originally created by the ancient and reclusive order of the heliomancers, as a means of bringing to gift of light to places where the sun does not reach. As for their myriad light sources, they have no clear origins, and may even be spontaneously produced by the keepers themselves through some unknown mechanism. Though the keepers are adept at navigating the treacherous terrain of the UnderDark, they often turn up damaged or outright destroyed; much of this is attributed to the Darklings, who see keepers as heretical harbingers of poisonous illumination, and whose policies strictly prohibit all non-infrared light sources below the Demarcation of Rouleigh.
